Here's an example using Enumerator#next:

a = [1, 0, 1, 1, 0, 0, 1]
b = ["101101", "101100", "110011", "000111", "010110"]

enum = a.cycle

b.each do |str|
  int_arr = str.split(//).map(&:to_i)

  result_arr = int_arr.map do |int|
    int ^ enum.next
  end

  p result_arr.join('')
end

--output:--
"000001"
"011010"
"101000"
"001010"
"110000"
